Texas church shooting: Trump expresses condolence, death toll expected to be more than 20

United States President Donald Trump has expressed his condolence for the victims of a mass shooting at a church in Texas' Sutherland Springs.

"May God be w/ the people of Sutherland Springs, Texas. The FBI & law enforcement are on the scene. I am monitoring the situation from Japan," Trump tweeted on Sunday.

The U.S. president is currently in Japan as part of his five-nation, 13-day tour of Asia.

Earlier, the local media reported that a shooting had taken place at the First Baptist Church of Sutherland Springs, about 65 km east of San Antonio.

Reportedly, more than 20 people were killed after a gunman walked into the church and opened fire.

The New York Times has quoted a official, Paul W. Pfeil, a Wilson County, Tex., commissioner, as saying that he did not have a total count of the number of dead in the shooting, but, he said, it was "more than 20."

Albert Gamez Jr., another Wilson County commissioner, told CNN that he was told by the police that the gunman was chased into the next county and was killed, but it was not clear whether the police shot him or he killed himself.

Gamaz said he was told by an emergency medical technician that 27 people were dead and 24 others were injured.
